Help! There will be a basketball match in our college. There are thirty classes in one class. How can we compete for the championship? (The activity funds are limited, and the shorter the schedule, the better). Thank you. The single elimination system is adopted, which requires the least number of games and the shortest schedule.

Divide 30 teams into two and a half districts, each district 15 teams. Timetable for every half month:

The first round of lottery 1 team, the remaining 14 teams compared 7 games, and 7 winning teams entered the top 16;

1/8 finals: 8 teams compared 4 games, and 4 winning teams entered the top 8;

1/4 finals: 4 teams played 2 games, and 2 winning teams entered the semi-finals;

Semi-final: 2 teams 1 game, and the winning team enters the final;

Final: 1 game.

* * * Requirements: 2× 7+2× 4+2× 2+2×1+1= 29 games.
